cubic grinder W storage chamber and keif catcher

i'm sorry for deleting the previous model but i ended up upgrading it with 4 layers instead of 3 so you can now collect your kief, i would suggests printing the 3rd piece before 1,2, and 4, already coded files are available so you can have the correct fine resolution for the small holes on piece 3 or so you keep strength and time on pieces 1,2, and 4
